Occult breast cancer: Unusually detected by left para sternal adenopathy

Occult breast cancer is a breast cancer that can often be revealed by axillary lymph node metastasis without a primary breast lesion.

Initially, the absence of a breast lesion was just clinical, but this definition has now been broadened to include the negativity of signs on mammography and ultrasound. management of patients with occult breast cancer is non-standardized and varied, ranging from simple surveillance to radical or conservative surgery, radiotherapy or systemic treatment. However, there is no consensus on the optimal management of these patients.

This type of cancer is usually detected by axillary adenopathy. We report a case of a non-routine occult breast cancer, detected after adenectomy of a left suprasternal adenopathy and not by axillary lymphadenectomy.

Our case showed other locations of occult breast cancer, other than axillary adenopathies, which remain the usual site of this type of cancer, illustrating that its natural history remains unclear.

Although there were variations in the management of our patient, given her particular context, our case illustrates the need for individualized treatment.
